Can loaches be released in rivers and what are the benefits of loach release?

Loaches can be released into rivers.

Loaches are not invasive alien species.

Nor are they ferocious fishes.

There are also many loaches in the natural waters.

Of course, China has a vast land and many places where there are no loaches, and it is better not to release loaches in these places, because they are cross-regional species invasion.

*Yes**, loaches can be released in rivers. Since loaches can perform intestinal respiration in addition to gills for breathing, it is highly tolerant of low dissolved oxygen environments. In a water-scarce environment, loaches can survive for a long time as long as the soil remains moist.

In rivers, loaches can find suitable waters and food for survival, so they can survive and live happily. However, the surrounding environment and other factors, such as suitability for loaches and local ecosystems, need to be considered when releasing to ensure that the loaches can survive and grow naturally after release.

There are many animals that can be released, but we must first understand what kind of environment the animal is suitable for survival, and we must not make good deeds into bad deeds, so we must first understand them before releasing them. Releasing loaches is also particular, and the habits of loaches:

Prefer to live in still water with thick silt. It inhabits paddy fields, ponds, lakes, marshes, rivers and other places with soft mud. Living in poorly lit mud, their eyes deteriorate and they rely only on their tentacles to find food.

Loaches can live in water or silt with very little dissolved oxygen, and in addition to gills respiration, they can also use ** and intestines to draw oxygen directly from the air. When the water temperature is high, the air pressure is low or the density is too large, and the dissolved oxygen in the water is insufficient, it can jump out of the water to swallow air and breathe through the intestines.

The suitable living water temperature for loaches is 20-30. When the water temperature is too high or too low, and when the weather is dry and shallow, they often dive into the mud layer to survive the unfavorable environment. Usually in addition to the lack of oxygen, infection and bad climate and other reasons, almost not the middle and upper layer of the water activities, winter when the pool water dries up, burrow into the soft mud, rely on a small amount of water to keep the first moist, and intestinal respiration to maintain life.

Loaches are omnivorous fish. The main food is small crustaceans, insect larvae, worms, algae, higher plant detritus, underwater humus, etc. The larval stage preys on animal feed, and then turns to omnivorous, and the adult loach mainly feeds on plant feed.

When the water temperature is above 15, the appetite gradually increases, and when it rises to 25-27, the appetite is particularly vigorous and grows rapidly. Once it exceeds 32, appetite decreases. Usually they feed at night, but during the reproductive period during the daytime, and the feeding of females increases significantly.

The first thing to pay attention to is to release the loach to a place with better water quality and less net catch, so as to prevent it from being caught again and make your release more meaningful.

Reasons why it is not recommended to release loaches:

1. The released animals are not adapted to the ecological environment of the release site and cannot survive.

2. The released animals survive and become invaders of the local ecology, destroying the local ecological balance.

Loaches are bottom-dwelling fish that inhabit the bottom of various shallow and silty environmental waters such as rivers, lakes, ditches, paddy fields, ponds and marshes. Diurnal and nocturnal, it is adaptable and can live in an environment rich in humus.

When there is a lack of oxygen in the water, it can jump to the surface of the water and swallow air for intestinal respiration. When the pool dries up, dive into the mud and do not die as long as the soil is kept moist with a small amount of water. Loaches are widely distributed in China, Japan, Korea, Russia and India along the Asian coast.

Morphological characteristics. The body is elongated, cylindrical, and the caudal peduncle is flattened and thin. Small head. Snout tip.

Lower mouth, horseshoe-shaped. 5 pairs of whiskers (1 pair of snout whiskers, 2 pairs of maxillary whiskers, 2 pairs of mandibular whiskers). The eye is small, laterally superior, covered by epithelium, without infraocular spines.

The gill aperture is small, and the gill slit terminates at the base of the pectoral fin. The scales are very small and deeply embedded in the skin. The siding line is complete.

Lateral line scales are more than 150. The swim bladder is small and enclosed in a hard bony sac.

The dorsal fin is short, the starting point is opposite to the beginning of the pelvic fin, with unbranched fin bars 2 and branched fin bars 7. The pectoral fin is distantly from the pelvic fin, with unbranched fin bars 1 and branched fin bars 10. The pelvic fin does not reach the anal fin, with unbranched fin rays 1, branched fins 5-6.

Anal fin with unbranched fin 2 and branched fin 5. The caudal fin is rounded.

1. Putting loaches can develop good moral character and increase compassion.

2. Putting loaches will return the loaches to nature, so that the loaches will work on nature, and the loaches are also a link in the biological chain, and overfishing of loaches will destroy the ecological balance.

Loaches should be released to choose a good living environment, loaches inhabit rivers, lakes, ditches, paddy fields, ponds and marshes.

and other shallow water and silt environment water bottom.

Precautions for release

1. First, pay attention to the principle of release. The principle of release is to release those animals, fish, birds, etc., which are easy to be killed and eaten by others, of course, some creatures that are destined to be encountered should also be rescued in time.

2. The second is to pay attention to the location of release. When releasing animals, it is necessary to study in advance, it is best to choose a place that is not easy to be captured, the water quality should be clean, and the environment should be hygienic.

3. The third is that off-site species, such as transnational and inter-provincial ones, should be handled cautiously, and it is not good to destroy the local ecological balance, have no natural enemies, and reproduce indefinitely, resulting in the extinction of other species, and the consequences are very serious. Confirm that it is safe to be released.

Loaches are adaptable to the environment and can survive in lightly polluted water, they can swallow air beyond the surface of the water and use intestinal respiration, and they can also survive in water bodies with severe eutrophication and hypoxia. Therefore, it is completely possible to survive if the loaches are released into the Yangtze River.

But loaches like to stir up sediment, and large numbers of loaches can cause damage to water bodies. Please investigate the actual situation of the local waters and release them scientifically.

Yes! Freshwater creatures can live, and the loaches in rivers and lakes are estimated to run into the Yangtze River.

It should be 100% fine, the loach is a particularly strong animal.
